Patented Feb. 17, 1953 UNITED STATES PATENT OFFICE 4 Claims.

My invention relates to toys that produce bubbles by blowing a thin filmof soapy liquid into globular shape- The soapy liquid maybe a solutionof soap in water ora solution or mixture of similar consistency andviscosity adapted for the formation of bubbles, and any such solution ormixture is. called a. soapy liquid in the following specification andclaims.

Objects of my invention are to facilitate the production of accuratelyshaped globular bubbles, to produce bubbles continuously in continuousseries and thereby to increase the entertaining. effect: of the toy.

Other objects are to use: a. frame for picking, up, carrying andreleasing a film of soapy liquid, and a blowing tube positioned out ofcontact with the soapy liquid, thereby to avoid the possibility thatsoapy liquid obstructs the blowing tube or is sucked back into the mouthof the blowing person, and further thereby utilizing the strong andstraight air flow produced by a blowing tube which air flow is much moreefficient than the air flow produced when a frame is swung by hand.

Further objects are to make the air flow more steady and lasting byproviding the blowing tube with a wide air space interposed between theinlet and the outlet of the tube, thereby to accumulate compressed airin the tube when the operator blows whereby the outlet of the tube willdischarge air for a short time after the operator has ceased blowing,and thereby to. facilitate the continuous production of bubbles.

Still other objects are to incorporate the blowing tube in the head of afigure simulating a living body, for example a person or an animal, touse the mouth of this figure head as outlet for the blowing tube,thereby to simulate a blowing living body, and thereby to increase theamusing effect of the toy.

Still further objects are to provide a toy of the mentioned nature thatcan be easily and inexpensively made and assembled, and that can beeasily operated by a child.

Still other objects and advantages will appear from the followingdescription of an exemplifying embodiment of my invention, from theappended claims and from the accompanying drawing in which:

Fig. 1 shows a top View of an illustrative embodiment of my invention.

Fig. 2 shows a front view of the same embodiment.

Fig. 3 shows a sectional side View of the same embodiment, this sectionbeing taken along the line 3-3 in Fig. 2.

Referring to the drawing, numeral I indicates a bowl or a similarreceptacle containing a soapy liquid 2. Bearings 4 form upperprojections of this bowls rim.

A shaft it passes. rotatably through the bearings 4 and has outer endsprovided with buttons 6 which may have cylindrical surfaces roughenedfor better grip. One or several arms I, for example, four arms areafiixed to the shaft 5 and extend from the shaft radially. Each arm 1terminates in a ring-shaped frame 8. The area surrounded by a frame 8lies in a plane that is radial with respect to the shaft axis. All arms1 have preferably the same length. This length is so measured that theframe carried by an arm immerges completely into the liquid 2 when thearm is. in downward extending position and that the. frame is positionedover the level of the liquidv when the arm isin upward extendingposition. Each of these positions corresponds. to one of the rotarypositions of the shaft.

A figure 9 simulating a living body, for example, a. boy is afiixed tothe bowl i. and may form an integral extension thereof. The figure 9 hasa hollow head H provided with an inlet opening l2 and an outlet openingl3. The inner space M of the head H is considerably wider than theseopenings whereby the head constitutes a blowing tube with a channelhaving a bulge-like widened median part. The outlet opening [3 simulatesthe mouth of the boy and. is. directed toward that frame. 8 which. is inthe most raised position. This direction is perpendicular to the areasurrounded by the frame. The inlet opening I2 is positioned in the rearof the head I- I. The rear head end containing the inlet opening maysimulate a hat tip I5 and may have an elongated shape suitable forinsertion into the mouth of the operating person.

The described toy operates as follows:

The operating person blows through the tip [5 and, at the same time,turns one of the buttons 6 in the direction of the arrow IS in Fig. 3.Thereby the shaft 5 and the arms 7 with the frames 8 are rotated in thesame direction. This rotation guides the frames 8 in a path that has astretch immerged in the liquid 2 and has another stretch positioned overthe level of the liquid. While passing through the liquid, each framepicks up a film of soapy solution which, then, is raised by the frameout of the liquid and which spans over the area surrounded by the frame.

When the frame reaches the position in front of the opening I3, the airblown from this opening in the direction of the arrow l! hits the filmwhereby the latter is inflated. An initial stage of the inflated film isshown in Fig. 3 at l8. Immediately thereafter, the film forms a globularbubble and separates from the frame as shown at [9. Each frame mayrelease one or several bubbles.

Continuation of the rotation continuously brings further film-carryingframes into position before the outlet I3 whereby a continuous pro- 3duction of bubbles results. This continuous production is facilitated bythe space M in the blowing tube which results in a more steady andlonger lasting air flow.

The blowing tube is permanently separated from the soapy liquid and ispermanently held in proper position. Hence the air hits the film alwaysefficiently and uniformly, and the soapy liquid can neither obstruct theblowing tube nor reach the mouth of the operator.

I desire it understood that my invention is not confined to theparticular embodiment shown and described, the same being merelyillustrative, and that my invention may be carried out in other wayswithin the scope of the appended claims without departing from thespirit of my invention as it is obvious that the particular embodimentshown and described is only one of the many that may be employed toattain the objects of my invention.

Having described the nature of my invention, what I claim and desire toprotect by Letters Patent is:

l. A bubble-producing toy comprising a bowl for a soapy liquid, a framemovably connected to said bowl and guided in a path having a stretchpositioned in said bowl under the level of said liquid, passing inupward direction through a part of the surface of said liquid whichforms a full area, and having another stretch positioned over said levelwhereby said frame when moved carries a soapy film out of said liquid,said frame surrounding an opening passing through said framesubstantially in the direction of said path and having a broad sidepositioned across said path direction, and a blowing tube afiixed tosaid bowl and having an outlet narrower than said frame and directedtoward said frame when the latter is positioned over the liquid level.

2. In a bubble-producing toy, a film-positioning device comprising abowl for a soapy liquid, and a frame movably connected to said bowl andguided in a path having a stretch positioned in said bowl under thelevel of said liquid, passing in upward direction through a part of thesurface of said liquid which forms a full area, and having anotherstretch positioned over said level whereby said frame when moved carriesa soapy film out of said liquid, said frame surrounding an openingpassing through said frame substantially in the direction of said pathand having a broad side positioned across said path direction.

3. In a bubble-producing toy, a film-positioning device comprising abowl for a soapy liquid, a horizontal shaft rotatably supported by saidbowl, a frame for carrying a film of said liquid, and an arm connectingsaid frame to said shaft whereby said frame is guided in a circularpath, said arm having such a length that said frame is immerged in saidliquid in one rotary position of said shaft and that said frame israised over the level of said liquid in another rotary position, saidframe surrounding an opening passing through said frame substantially inthe direction of said path and having a broad side positioned acrosssaid path direction.

4. A bubble-producing toy comprising a bowl for a soapy liquid, a framerotatably connected to said bowl and guided in a circular endless pathhaving a stretch positioned in said bowl under the level of said liquid,passing in upward direction through a part of the surface of said liquidwhich forms a full area, and having another stretch positioned over saidlevel whereby said frame when moved carries a soapy film out of saidliquid, and a blowing tube affixed to said bowl having a median partforming a bulgelike, considerably widened inner space and having anoutlet narrower than said frame and directed toward said frame when thelatter is positioned over the liquid level.
